DETAILED DESCRIPTION

Various embodiments disclosed herein relate to fixtures such as toilets that include a lighting mechanism for illuminating portions of the fixture to facilitate use of the fixture by users. For example, a lighting mechanism may be integrated into a toilet seat hinge component such that light is transmitted outward from the hinge component in one or more directions (e.g., toward the toilet bowl, toward the toilet tank, etc.). Such lighting may be useful in low light conditions to provide a “guide light” to direct a user toward the toilet or a “task light” for use of the toilet. Certain embodiments may provide better illumination than existing lighting mechanisms, better lighting efficiency, or may improve the performance or life of power sources that may power the lighting mechanisms given the better illumination.

In certain embodiments, hinge assemblies disclosed herein may provide a stable and securely mounted lighting mechanism having a relatively easy installation. For example, the lighting mechanism may be at least partially contained within the hinge of the toilet seat assembly by means of protrusions, etc., ensuring a positive connection between components. Furthermore, in certain embodiments, by acting as a “guide light” or a “task light,” particularly in low light conditions, a user may be able to easily locate the toilet, easily know whether the seat lid or ring are in an open (e.g., up) position, or have a clear indication of an allowable area for use of the toilet.

Referring now to FIG. 1 and FIG. 2, a toilet 100 is shown according to an example embodiment. Toilet 100 includes a base 101 including a bowl 110 (shown in FIG. 2), a tank 102 (shown in partial cut-away) coupled to base 101, and a seat assembly 103. Seat assembly 103 includes a lid 104, a ring 105, and a hinge assembly 106. Hinge assembly 106 includes a housing 112. Hinge assembly 106 connects seat assembly 103 to base 101 such that lid 104 and ring 105 are pivotable between a closed position (as shown in FIG. 1) and an open position (as shown in FIG. 2). Lid 104 and ring 105 are independently pivotable.

Hinge assembly 106 includes a lighting mechanism 107. Lighting mechanism 107 is at least partially encapsulated in, partially enclosed in, or otherwise partially disposed within housing 112 of hinge assembly 106. In certain embodiments, lighting mechanism 107 is configured to direct light 108 toward tank 102 and, in certain embodiments, light 108 may be reflected off of tank 102. Light 108 may act, among other things, as a “guide” light to the toilet such that a user may be able to locate the toilet in a dark room. In certain embodiments, lighting mechanism 107 may be configured to direct light 109 into an interior of the bowl 110 (as shown in FIG. 2). In certain embodiments, light 109 may be reflected off of the interior of the bowl 110. Light 109 that is directed into bowl 110 may act, among other things, as a “task” light such that the bowl 110 is illuminated for enhanced user aiming in a dark room. In certain embodiments, when lid 104 and ring 105 are in the closed position, light 109 may be directed away from the toilet through gaps between base 101, ring 105, and lid 104 (as shown in FIG. 1). Referring now to FIG. 3, a magnified view of hinge assembly 106, including hinge housing 112 and lighting mechanism 107, is shown, for use with the toilet 100 of FIGS. 1 and 2.

Referring to FIG. 4, FIG. 5 and FIG. 6, additional details of lighting mechanism 107 are shown according to example embodiments. In certain embodiments, lighting mechanism 107 includes a light source 401 (e.g., an LED or any other type of light source). In certain embodiments, lighting mechanism 107 may also include a lens 410. Lens 410 may include, in certain embodiments, a curved portion 411 configured to “bend” or otherwise direct light 109 from light source 401 downwardly toward a toilet bowl, such as toilet bowl 110 of FIG. 2 (light 109 is not shown in FIG. 4 given that light source 401 is shown in an off state in FIG. 4; light 109 is shown in FIG. 5 and FIG. 6 where light source 401 is shown in an on state, as well as, for example, in FIG. 2). In certain embodiments, curved portion 411 may at least partially extend outside of hinge housing 112, as can be appreciated in FIG. 3 and FIG. 2. In certain embodiments, curved portion 411 may at least partially extend into an area above the opening of a toilet bowl, such as the area above the opening of toilet bowl 110, as can be appreciated in FIG. 2. In certain embodiments, lens 410 may include a rippled surface 412 at a location approximately in front of light source 401, configured to disperse light 109 from light source 401. In certain embodiments, light source 401 may point in a direction approximately perpendicular to the rippled surface 412.

In certain embodiments, as shown in FIG. 4, curved portion 411 may include curved side surfaces 411 b and 411 c. Each of the curved side surfaces 411 b and 411 c may generally have a profile that slants rearwardly with rounded corners, as seen from a top view, in the manner of an “s-shape” or the like, such that the side surface curves in one direction and also curves in an opposite direction, tapering back into a portion of the body of lens 410 that may be approximately flush with hinge housing 112. In certain embodiments, such side surfaces 411 b and 411 c may be intended to direct light 109 at least to lateral sides of bowl 110.

In certain embodiments, lighting mechanism 107 may include a light source 402, configured to emit light 108 at a toilet tank, such as toilet tank 102 shown in FIG. 1 (light 108 is not shown in FIG. 4 given that light source 402 is shown in an off state in FIG. 4; light 108 is shown in FIG. 5 where light source 402 is shown in an on state, as well as, for example, in FIG. 1). In certain embodiments, lighting mechanism 107 may also include a lens 420. Lens 420 may include in certain embodiments a rippled surface 421 at a location approximately in front of the light source 402, configured to disperse light 108 from the light source 402. In certain embodiments, light source 402 may point in a direction approximately perpendicular to the rippled surface 421.

In certain embodiments, the inward offset location of the rippled surface 412 in relation to the perimeter of lighting mechanism 107 may be different than as shown. Different distances between the rippled surface 412 and the perimeter of lighting mechanism 107 may alter the width of the projected light 109 through lens 410. In a similar fashion, in certain embodiments, the inward offset location of the rippled surface 421 in relation to the perimeter of lighting mechanism 107 may be different than as shown. Different distances between the rippled surface 421 and the perimeter of lighting mechanism 107 may alter the width of the projected light 108 through lens 420. In certain embodiments, the flat surfaces shown in FIG. 4 that extend from the rippled surface 412, or that extend from rippled surface 421, may be shaped differently than as shown. For example, the surfaces may be altered, bent, curved or shaped in other ways, further affecting the dispersion of light 109 or light 108.

Light sources 401 and 402 may be powered by any power source, such as, for example, one or more batteries, current from an electrical outlet, or any other power source. In certain embodiments where light sources 401 or 402 are powered by one or more batteries, the one or more batteries may be placed within hinge assembly 106, including in some embodiments within hinge housing 112. In certain embodiments, the light sources 401 and 402 may be programmed to run at the same or different times, or at the same or different intensities to cater to a desired performance or efficiency. In certain embodiments, lighting mechanism 107 may include sensors that may detect if lid 104 is up or down, or sensors that may detect other conditions. Further, in certain embodiments, lighting mechanism 107 may include programming, smart controls, or Bluetooth to provide feedback and dynamically alter the performance or intensity of light sources 401 or 402 depending on inputs from sensors. For example, the light sources may be automatically turned on or off, or the intensity may be automatically lowered or increased depending on whether lid 104 is up or down. In other embodiments, the light sources may be automatically turned on, off, or adjusted depending on other sensor inputs. For example, the sensors may be motion sensors or proximity sensors operably coupled to the light source(s). According to one embodiment, the sensors may provide a signal to increase the intensity of the illumination of the light source as a person approaches the toilet and to decrease the intensity of the illumination as a person leaves the area. By further way of example, the sensors may also be photosensitive and enable the light source to illuminate only below a predetermined background light threshold. According to other embodiments, the light source may have different color capabilities (e.g. multi-color LEDs), in order to impart an enhanced visual or aesthetic appearance to the bathroom décor. Any one or more of these sensors or features may be selectively programmed or modified by a user (e.g. through Bluetooth communication via a smartphone app to a control device or interface associated with the light source, etc.). All such functionalities and capabilities are intended to be within the scope of this disclosure.

In certain embodiments, lens 410 or lens 420 may be made of a transparent or a semi-transparent material, such as, for example, acrylic, poly carbonate, glass, or any other transparent or semi-transparent materials. In certain embodiments, lens 410 or lens 420 may be made of materials that are not transparent or semi-transparent. In certain embodiments, lens 410 or lens 420 may be made of a combination of materials, such as transparent, semi-transparent or non-transparent materials. In certain embodiments, lens 410 or lens 420 may be made by the same material and may form part of a unitary body. In certain embodiments, lens 410 or lens 420 may be disconnected or connected to each other via additional components.

Referring further to FIG. 5, additional details of lighting mechanism 107 are shown according to example embodiments, including additional details of rippled surface 412 and rippled surface 421 according to example embodiments. In certain embodiments, rippled surface 412 may be configured to disperse light 109 from light source 401, and rippled surface 421 may be configured to disperse light 108 from light source 402. An example embodiment is illustrated in FIG. 5. In certain embodiments, rippled surface 412 or rippled surface 421 may include one or more arched surfaces (shown in FIG. 5 as a series of arches arranged in a parallel pattern). In certain embodiments, rippled surface 412 or rippled surface 421 may include one or more angled surfaces forming a “jagged” surface. In certain embodiments, rippled surface 412 or rippled surface 421 may include a combination of these or other shapes intended to disperse light, such as one or more curbed surfaces and one or more angled surfaces.

Referring further to FIG. 6, a cross-section showing additional details of lighting mechanism 107 is shown according to example embodiments, including additional details of curved portion 411 according to example embodiments. In certain embodiments, curved portion 411 may be configured to “bend” or otherwise direct light 109 from light source 401 downwardly toward a toilet bowl, such as toilet bowl 110 of FIG. 2, by acting as a light guide. As can be seen in FIG. 6, curved portion 411 may be configured to act as a light guide by allowing light 109 to travel through curved portion 411, thereby directing light 109 from light source 401 toward the toilet bowl. As can be seen in FIG. 6, in certain embodiments, curved portion 411 may also or alternatively be configured to “bend” or otherwise direct light 109 from light source 401 downwardly toward the toilet bowl, by including a surface 411 a configured to allow light 109 from light source 401 to “bounce” or reflect toward the toilet bowl. While FIG. 6 depicts light 109 bouncing from a lower surface 411 a of curved portion 411, in certain embodiments, light 109 may “bounce” or reflect from any surface of curved portion 411.

Referring to FIGS. 8-10, alternative example embodiments of lighting mechanism 107 are shown. As shown in FIGS. 8-10, lens 410 or lens portion 411 may be shaped differently than in the example embodiments shown in FIGS. 2-4, to “bend” or otherwise direct light from light source 401 toward a toilet bowl, such as toilet bowl 110. In FIGS. 8-10, lens portion 411 is wider than in the embodiments shown in FIGS. 2-4 to provide a different distribution of light 109 from light source 401 into the bowl 110. In other embodiments, other shapes for lens 410 or for lens portion 411 may be used.

Referring to FIG. 7 and FIG. 11, example embodiments of lighting mechanism 107 are shown from an angle under lighting mechanism 107. In certain embodiments, as shown in FIGS. 7 and 11, at least a portion of lower surface 411 a of curved portion 411 (shaped differently in FIG. 7 and FIG. 11), or the entire lower surface 411 a of curved portion 411, may be textured. This texture, for example, is intended to diffuse light 109 from light source 401. In certain embodiments, as shown in FIGS. 7 and 11, additional portions of a lower surface of lighting mechanism 107, or an entire lower surface of lighting mechanism 107, may be textured. In certain embodiments, lower surface 411 a or lower surface of lighting mechanism 107 may not be textured.
